Handcrafted
Beneath the surface of Cinema HD’s elegant exterior lies rigid MDF
construction. Interlocking joinery maximizes the strength of the cabinet parts.
Polyester fiberfill is selected for internal damping. A sharp rap on the
enclosure will leave you with little more than bruised knuckles.
Each cabinet is impeccably finished on all exposed surfaces with select
veneers. The exquisite finish is hand-rubbed several times to assure a patina
at home with the most elegant decor.

Unpacking Your Speakers
Your new
speaker system
has been very carefully packaged
to insure
that it travels
to you safely. Each
speaker is protected
by a double-
wall
outer carton with
heavy V-board corner
protectors. Molded foa
m
end caps are used to
protect
the elegant cabinetry,
and a plastic liner
is provided as waterp
roofing. Please save this packing for future
transportation. If
cartons become damaged
or misplaced,
new ones
can be
purchased
from Legacy Audio.

Speaker Placemen
t
To allow
more
flexibility in seating arrangements,
your Legacy loudspeaker i
s
designed
for broad lateral
coverage. Optimal listener position is actually about 5 to
15
degrees
off of the axis n
ormal
to the loudspeaker baffle (approximately 4-5’ off
the fl
oor).
Your Legacy
speaker is optimized
for a flat response in
the far field.
Placing the loudspeaker or the listener near a room
boundary
will generally increase
low frequency impact. You may also wish to
reduce low
frequency output with you
r
preamp's
bass tone control.

Hooking Up Cable
s
The ideal conductor would have negligible resistance, inductance
and capacitance.
The table below shows how a few actual speake
r
cables
measure up.
Cable
Ωs/ft pF/ft µH/ft
Capacitance is considered insignificant in
each cable
because its ef
-
fect is well
out of the audio bandwidth; i
nductance
can be de
-
creased
(at the
expense
of increased capacitance) by keeping the
conductor pair closely spaced.
How long would a cable have to be before inductance
effects woul
d
impinge on the audio spectrum? Approximately 300 feet of 12 gauge
would
be required to establish
a corner
frequency
of 20 kHz with an
8 Ohm loudspeaker. As
you see, inductance is not a problem fo
r
most of us.
9
Hooking Up Cable
s
What about
phase shift
due to
frequency dependent travel times
down the speaker
cable? Measurements show that 100 Hz waves
will
be delayed about 20 billionths of
a
second behind 10 kHz waves when traveling to the end of a 10 foot
speaker cable.
Since
the
cilia
of the ear requires 25,000 times longer than this
just to transmit phase
inf
ormation, phase shifting is obviously not the primary concern when considering
speaker cables.
What about resistance?
Finally
we are getting
somewhere. Resistance is the control
-
ling factor of the amplifier/loudspeaker interface. Excessive resistance can cause ma
-
jor shifts
of
speaker crossover frequencies. The lower the impedance of the loud-
speaker,
the
greater
the effects of series resistance. A
20 foot run of 18
gauge cabl
e
can cause up to 10% deviations
of
crossover center frequencies. That same 20 fee
t
can
un-damp
your damping
factor and
reduce
your system
s’
output
by one half deci-
bel.
In
summary,
there are no perfect cables. The best way to approximate the ideal
would
be to keep loudspeaker leads
as short as is practical.
10
Amplificatio
n
Ideally
the loudspeaker would
be among the first
components selected
when assembling a play
-
back
system. This would allow the user to choose an amplifier capable
of delivering adequate
amounts
of
current into
the
frequency dependent load
presented
by the loudspeaker. However
,
when
upgrading a
system, audiophiles
may find themselves matching their
new loudspeakers to
their existing amplification.
For this reason, extensive
measures
have been taken to
ensure that
each Legacy speaker system represents a smooth, non-reactive load
to virtually
any amplifier.
Often
there is
much confusion regarding amplification and loudness levels.
It should
be
under-
stood that the role of the amplifier
goes beyond that of driving loudspeakers to a given so
und
pressure level.
The amplifier should be able
to
CONTROL
the loudspeakers across the entire mu-
sic spectrum. This means
that
parameters
such as damping
factor (values
greater
than 60 ar
e
acceptable) and dynamic
headroom should
not be overlooked
when comparing amplifiers.
11
Amplificatio
n
How much power
will
your new
speakers need?
That ultimately depends on
your listening environment
and musical
tastes.
As little
as five
watts pe
r
channel should drive
them to a level satisfactory for
background music.
A
typical
45 watt per channel receiver may
fill
a room with
the compressed
mid-band
energy of “heavy metal,” but seem to lack weight
or control with
classical recordings. Some audiophiles feel
that 200 watts per channel is th
e
bare minimum to avoid audible clipping distortion
when reproducing music
at “live” playback levels. Your Legacy speakers
are designed to take advan-
tage of “high-powered” amplifiers,
so do
n’t
be afraid
to put them through
their paces.
How much is
too much power? Rarely is a drive unit
damaged
by larg
e
doses
of music power. More often than not the
villain is amplifier clippi
ng
distortion. Even
through decades
of refinement, loudspeakers
are
still noto
-
riously inefficient
transducers, requiring huge
amounts
of power to recreate
the impact
of the
live
performance.
Typically less that 1% of electrical
power is
converted into acoustic
output.
(For example,
an
omnidirectiona
l
transducer with
an anechoic sensitivity of 90 dB @ 1w/1m has a
full spac
e
efficiency
of only 0.63%)
12
Amplificatio
n
When an amplifier is unable to
fulfill
your loudspeakers demands,
a
damaging harmonic spike may be leaked to the high
frequency drivers.
Another important point regarding loudness is that the dB scale is a
logarithmic
one. This means
that a 150 Watt amplifier will potentially sound
only twice as loud as a 15 Watt amplifier. If
all
of this discussion
of powe
r
and lo
udness seems a bit abstract, consider
the example below.
The average acoustical
power developed by a person speaking in
a
conversational tone
corresponds
to a mere 0.00001 Watts. The power that
would
be developed by the entire population of the city of New Yor
k
speaking at once would barely illuminate a single
100 Watt light bulb.

Speaker Connection
s
The Terminal Plate
At the rear of your loudspeaker you
will find a terminal plate housing two
rows of
jumpered binding posts.
The upper row is
the input to
the
"sate
llite" portion
of the
speaker.
The lower row is
the input to th
e
"subwoofer" portion
of the
speaker.
When left in place,
the factory installed
jumper bars allow
the
speaker
to be driven with a single channel
of amplification. (If biamping,
or biwiring,
be sure to remove the jumpe
r
bars.)
Connect each channel
of your amplifier
to a loudspeaker via the five-way
gold binding posts provided. Dual
banana plugs
or gold plated
spade lug
s
are
recommended means
of termination. Be sure that you
observe polarit
y
when making the connections. The positive (+) terminal
of the amplifier
should be
connected
to the positive terminal
of the loudspeaker. The
negative (-) terminal of the amplifier should be
connected
to the negative
terminal
of the loudspeaker.
14
Fine T
unin
g
To facilitate
proper
set-up
of your
speakers in
a variety of room situations
,
we have included several heavy duty toggle switches
on the terminal plate,
located
on the back of the loudspeaker. All switches in the “up” position
represent
the “anechoic flat” position.
TREBLE Trim: - Nominally flat in the up position
- Negative 2dB at 10 kHz in the down position
(shelving for brighter rooms)
BASS Trim: - Nominally flat in the up position
- Negative 2dB at 60 Hz in the down position
(also raises impedance for budget receivers)
